Objectives : The purpose of this study was to gain an understanding of the effects of three exercise types on anthropometric and serum lipids and physiological index factors, which are known to be the three risk factors of cardiovascular disease in male workers. Methods : The experimental study period was 12 weeks. In this study, 30-40's males (N=31) were assigned to 3 experimental groups: regular aerobic(treadmill walking) exercise group, regular anaerobic(muscular endurance) exercise group, irregular aerobic & anaerobic exercise group and a control group using a stratified random assignment method. Results : In relation to anthropometric factors, the regular aerobic & anaerobic exercise groups showed significant decreases in Weight, Broca's index, WC, BMI, WHtR, WHpR and HRrest. With regard to the serum lipid factors, the TC was decreased, but the HDL-c increased among the regular aerobic & anaerobic exercise groups. However, no significant difference was found between the other groups in respect to the LDL-c and TG. Considering the physiological factors, the TC/HD-c, TC-HDL/HDL-c, LDL-C/HDL-c and NON-HDL-c ratios were decreased, but the HDL-c/TC ratio increased among the regular aerobic & anaerobic exercise groups. The TG/HDL-c and HDL-c/LDL-c ratios showed no significant differences between the groups. These results indicated that the positive change for each factor is much larger in the regular exercise groups, especially in the anaerobic exercise group. Conclusions : The results indicate that not only regular aerobic exercise, but also regular anaerobic(muscular endurance) exercise could be utilized in lessening the deleterious effects of the risk index factors for cardiovascular disease.

Purpose: In this study cardiovascular health status and health behavior of Korean women based on their household income were explored. Methods: For this cross-sectional study, 91 women residing in the community were recruited to complete survey questionnaires and biophysical tests including blood pressure (BP), body mass index (BMI), body fat rate, waist circumference (WC), and blood chemistry tests. Results: Compared to non-low income women (NLIW), low income women (LIW) were more likely to be older, less educated, and jobless, and further more LIW were postmenopause and reported having been diagnosed with hypertension or hypercholesterolemia. Significant differences were found in systolic BP, triglyceride level, BMI, body fat rate, and WC between the groups. Two fifths of the LIW had indications for metabolic syndrome. Their 10-yr risk estimate of myocardioal infarction or coronary death demonstrated a higher probability than that of NLIW. Although these significant differences were due to age gap between the groups, advanced age is known to be one of the key characteristics of LIW as well as a non-modifiable risk factor. Conclusion: Effective community programs for vulnerable women at risk of cardiovascular disease should be based on strategies targeting unhealthy behaviors and modifiable risk factors.

1. Objectives: This study is to investigate the relationship between Intima Media Thickness(IMT) of common carotid artery and Sasang Constitution. 2. Methods: 839 persons, over 40 years old, participated in community-based cohort of Korea Genome and Epiedemiology Study (KOGES) in Wonju City and Pyeongchang City of South Korea from June 2006 to February 2008. The diagnosis of Common carotid Intima Media Thickness was evaluated by B Mode ultrasonography, cardiovascular risk factors were checked using questionnaire and blood samples. Constitution was verified by a Sasang constitution specialist according to the results of PSSC(Phonetic System for Sasang Constitution), facial photos and a simplified Sasang constitutional questionnaire. Multiple regression analysis and logistic regression analysis were performed with SPSS. 3. Results: There were significantly high values in waist circumference, fasting blood sugar, systolic blood pressure, diastolic blood pressure, triglyceride, HOMA-IR and hsCRP in Taeeumin and low in HDL-cholesterol and adiponectin in Taeeumin. There were significantly high value in Common Carotid Intima Media Thickness in Taeeumin. Age was the significant cardiovascular risk factor irrespective of Sasang constitution in all participants. There was a positive correlation between smoking and Soyangin in all participants and men. There were positive correlations between LDL-cholesterol, BMI and Taeeumin in all participants and men. There were positive correlations between hsCRP and Soeumin in all participants and men. There was significantly high odds ratio of Taeeumin over Soeumin in common carotid Intima Media Thickness. 4. Conclusions: Regimens on cardiovascular diseases should be considered according to Sasang constitution. There are more sensitive risk factor in each constitution; smoking in Soyangin, LDL-cholesterol and BMI in Taeeumin, hsCRP in Soeumin.

A total of 40 patients having a diagnosis of atherosclerotic coronary arterial disease were analysed on the operative outcomes according to variables as follows: 1) preoperative risk factors such as age, sex, CCS (Canadian Cardiovascular Society) functional class, type of angina, number of diseased vessel, presence of left main coronary artery stenosis, previous history of habitual smoking and presence of other medical diseases (diabetes mellitus, essential hypertension), 2) preoperative management such as intravenous infusion of nitroglycerine, preoperative IABP (intra-aortic balloon pump) support and whether the operation was scheduled as emergency or not, 3) intraoperative variables such as infusion method and composition of cardioplegic solutions, number of distal anastomosis, use of internal mammary artery, total cardiopulmonary bypass time and total cross clamp time. Complications included operative death in 12.5％, perioperative myocardial infarction in 25.0％ and perioperative arrhythmia in 17.5％. Nineteen perioperative variables were analyzed to identify risk factors for these end points. For operative death, presence of left main coronary artery stenosis (p = 0.056) and cardiopulmonary bypass time (p = 0.029) were significant in the univariate analysis, but presence of left main coronary artery lesion (p = 0.011, $\chi$$^2$= 6.45) and abscence of preoperative of IABP support (p = 0.069, $\chi$$^2$ = 3.30) were independent predictor in multivariate analysis (stepwise linear logistic regression).

Background: Recently, many surgeons have chosen sublobar resection for the curative treatment of lung tumors with ground-glass opacity, which is a hallmark of lepidic lung cancer. The purpose of this study was to evaluate the oncological results of sublobar resection for non-lepidic lung cancer in comparison with lobectomy. Methods: We conducted a retrospective chart review of 328 patients with clinical N0 non-small cell lung cancer sized ${\leq}2cm$ who underwent curative surgical resection from January 2009 to December 2014. The patients were classified on the basis of their lesions into non-lepidic and lepidic groups. The survival rates following lobectomy and sublobar resection were compared within each of these 2 groups. Results: The non-lepidic group contained a total of 191 patients. The 5-year recurrence-free survival rate was not significantly different between patients who received sublobar resection or lobectomy in the non-lepidic group (80.1% vs. 79.2%, p=0.822) or in the lepidic group (100% vs. 97.4%, p=0.283). Multivariate analysis indicated that only lymphatic invasion was a significant risk factor for recurrence in the non-lepidic group. Sublobar resection was not a risk factor for recurrence in the non-lepidic group. Conclusion: The oncological outcomes of sublobar resection and lobectomy in small-sized non-small cell lung cancer did not significantly differ according to histological type.

Objectives: The object of this study is to assess the relationship between socioeconomic factors and the predicted 10-year risk of cardiovascular disease by using health risk appraisal of ischemic heart disease. Methods: The study population was taken from The 2001 Korea National Health and Nutrition Survey, and it consisted of 1,566 men and 1,984 women aged 30-59. We calculated 10-year risk using the risk function of ischemic heart disease as developed by Jee. The educational level and equivalized household income were dichotomized by a 12 years education period and the median income level. Occupation was dichotomized into manual/non-manual work. We stratified the population by age(10 years) and sex, and then we rated the risk differences according to socioeconomic factors by performing t-tests for each strata. Results: There were gradients of the predicted 10-year risk of ischemic heart disease with the educational level and the equivalized household income, and thet was an increasing tendency of risk differences with age. Manual workers didn't show significant risk difference from non-manual workers. Conclusions: There was definite relationship between low socioeconomic position and the predicted risk of ischemic heart disease in the future.

Background: Ventilator-associated pneumonia (VAP) is a common disease that may contribute to morbidity and mortality among trauma patients in the intensive care unit (ICU). This study evaluated the associations between trauma factors and the development of VAP in ventilated patients with multiple rib fractures. Methods: We retrospectively and consecutively evaluated 101 patients with multiple rib fractures who were ventilated and managed at our hospital between January 2010 and December 2015, analyzing the associations between VAP and trauma factors in these patients. Trauma factors included sternal fracture, flail chest, diaphragm injury, traumatic aortic dissection, combined cardiac injury, pulmonary contusion, pneumothorax, hemothorax, hemopneumothorax, abbreviated injury scale score, thoracic trauma severity score, and injury severity score. Results: Forty-six patients (45.5%) had at least 1 episode of VAP, 10 (21.7%) of whom died in the ICU. Of the 55 (54.5%) patients who did not have pneumonia, 9 (16.4%) died in the ICU. Using logistic regression analysis, we found that VAP was associated with severe lung contusion (odds ratio, 3.07; 95% confidence interval, 1.12 to 8.39; p=0.029). Conclusion: Severe pulmonary contusion (pulmonary lung contusion score 6-12) is an independent risk factor for VAP in ventilated trauma patients with multiple rib fractures.

Background: This study investigated the clinical outcomes of surgical treatment of primary chest wall soft tissue sarcoma (CW-STS). Methods: Thirty-one patients who underwent surgery for CW-STS between 2000 and 2015 were retrospectively reviewed. The disease-free and overall survival rates were estimated using the Kaplan-Meier method, and prognostic factors were analyzed using a Cox proportional hazards model. Results: The median follow-up duration was 65.6 months. The most common histologic type of tumor was malignant fibrous histiocytoma (29%). The resection extended to the soft tissue in 14 patients, while it reached full thickness in 17 patients. Complete resection was achieved in 27 patients (87.1%). There were 5 cases of local recurrence, 3 cases of distant metastasis, and 5 cases of combined recurrence. The 5-year disease-free rate was 49%. Univariate analysis indicated that incomplete resection (p<0.001) and stage (p=0.062) were possible risk factors for recurrence. Multivariate analysis determined that incomplete resection (p=0.013) and stage (p=0.05) were significantly associated with recurrence. The overall 5- and 10-year survival rates were 86.8% and 64.3%, respectively. No prognostic factor for survival was identified. Conclusion: Long-term primary CW-STS surgery outcomes were found to be favorable. Incomplete microscopic resection and stage were risk factors for recurrence.

Background: Delirium is a recognized neurological complication following cardiac surgery and is associated with adverse clinical outcomes, including elevated mortality and prolonged hospitalization. While several clinical risk factors for post-cardiac surgery delirium have been identified, the pathophysiology related to the immune response remains unexamined. This study was conducted to investigate the immunological factors contributing to delirium in patients after thoracic aortic surgery. Methods: We retrospectively evaluated 43 consecutive patients who underwent thoracic aortic surgery between July 2017 and June 2018. These patients were categorized into 2 groups: those with delirium and those without it. All clinical characteristics were compared between groups. Blood samples were collected and tested on the day of admission, as well as on postoperative days 1, 3, 7, and 30. Levels of helper T cells (CD4), cytotoxic T cells (CD8), B cells (CD19), natural killer cells (CD56+CD16++), and monocytes (CD14+CD16-) were measured using flow cytometry. Results: The median patient age was 71 years (interquartile range, 56.7 to 79.0 years), and 21 of the patients (48.8%) were male. Preoperatively, most immune cell counts did not differ significantly between groups. However, the patients with delirium exhibited significantly higher levels of interleukin-6 and lower levels of tumor necrosis factor-alpha (TNF-α) than those without delirium (p<0.05). Multivariate analysis revealed that lower TNF-α levels were associated with an increased risk of postoperative delirium (p<0.05). Conclusion: Postoperative delirium may be linked to perioperative changes in immune cells and preoperative cytokine levels. Additional research is required to elucidate the pathophysiological mechanisms underlying delirium.
